For the Bayou, a San Francisco nonprofit organized last year to raise money to restore Louisiana's rapidly disappearing wetlands, recently held its first Cajun Cup Polo Tournament at Cerro Pampa Polo Club. The 150 attendees enjoyed buckets of Louisiana Gold Band Oysters, jambalaya and Cajun roast beef sandwiches while listening to zydeco musician and poet Zachary Richard, who flew his band out to the Petaluma site for the event. It included auctions of artwork by artists from the Bay Area, the bayou and beyond, raising about $10,000 for the cause.
